Embodiment 1

[0014] Such as figure 1 As shown, it includes a back plate 1 and a friction plate 2 , an induction wire 3 is arranged at the extreme position of the friction plate 1 , and an alarm device 4 is connected to both ends of the induction wire 3 .

[0015] In this embodiment, the induction wire 3 is a high temperature resistant wire.

[0016] In this embodiment, the alarm device 4 is an audible and visual alarm.

Embodiment 2

[0018] Such as figure 2 As shown, it includes a back plate 1 and a friction plate 2 , an induction wire 3 is arranged at the extreme position of the friction plate 1 , and an alarm device 4 is connected to both ends of the induction wire 3 .

[0019] In this embodiment, the induction wire 3 is a high temperature resistant wire.

[0020] In this embodiment, the alarm device 4 is an audible and visual alarm.

[0021] A brake pad with an early warning device according to the present invention has the beneficial effect that: when the friction pad is worn to the limit position, the induction wire arranged in the friction pad contacts the brake disc to form a current with the brake disc. loop, the alarm system detects the current loop, and then sends out an audible and visual alarm to remind maintenance personnel to replace the brake pads in time, effectively avoiding safety accidents caused by brake failure caused by brake pad failure. In addition, because the induction wires ar...

Abstract

The invention discloses a brake pad with a pre-warning device. The brake pad comprises a back plate and a friction plate. The brake pad is characterized in that an induction wire is arranged at the extreme position of the friction plate, and alarm devices are connected to two ends of the induction wire. When the friction plate is worn to the extreme position, the induction wire arranged in the friction plate is in contact with a brake disc, so that the friction plate and the brake disc form a current loop; after an alarm system detects the current loop, the alarm system sends out sound-light alarm to remind of immediately replacing the brake pad, so that safety accidents caused by failure of the brake due to failure of the brake pad is effectively avoided. In addition, as the induction wire is uniformly arranged in the whole friction plate, the alarm device can be triggered no matter which position is worn to the extreme position, so that risks are avoided.

Description

technical field [0001] The invention relates to a brake pad for a vehicle, in particular to a brake pad with an early warning device. Background technique [0002] Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The friction blocks are composed of friction materials and adhesives. When braking, they are squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of vehicle deceleration and braking. Since the friction material is constantly worn, its thickness becomes smaller and smaller. When the thickness reaches a certain limit, the brake pads must be replaced in time. Therefore, during use, maintenance personnel need to check and replace regularly, and the operation is cumbersome. If the inspection is not timely, the wear degree of the brake pads will be increased, which will lead to the failure of the industrial safety brake disc, and there is a great potential safety hazard. At present,...
